Really scared.... Postpartum preeclampsia

I had my baby on Monday. She is perfect in every way but I myself have not been feeling well. I called my doctor today because I had a headache that wouldn't go away along with some pretty swollen feet. She told me to get checked out at urgent care. My labs came back not so good and my blood pressure is high. I didn't know that there was even such a thing as postpartum preeclampsia!!! I am now being re-admitted to the hospital for treatment. I am so worried about my baby and what they are going to do to help me feel better. I am breast feeding and i want to keep it that way.
